1 Claim.

My present invention relates to improvements in applicators for use with therapeutic machines, in radiating high frequency electric currents in waves or rays, especially for benificial treatment of the human body and its organs. The applicator, which is used in connection with a therapeutic machine (not shown) is manually controlled or manipulated, and one of the essential features of the present applicator is the facility with which the instrument may be adjusted to vary the intensity and at the same time maintain a uniformity in distribution of the waves or rays from the applicator.

As it is well known to those familiar with the art, different results are acquired by the use of applicator when the latter is located at various distances from the subject being treated, and the purpose of my invention is to provide means whereby the head of the applicator from which the rays emanate may readily be adjusted for this purpose. After adjustment on a gaging post or support, the electrode head is retained in the desired adjusted position, always at the predetermined distance from the subject being treated, thereby simplifying the work of the operator and insuring accuracy in the treatment.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. In the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a view showing the applicator sup-- ported on the gage bar in position for use and indicating by dotted lines the flow of the rays or waves from the applicator head.

Figure 2 is an enlarged view with parts in section, disclosing the means for adjusting the applicator head on its gagepost or support.

Figure 3 is a view showing a fragment of hollow head of the applicator, with the electrodes thereon.

In carrying out my invention I preferably use a hollow head 1 fashioned in ooncavo-convex form, with a convex exterior face, and having the shape of a segment of a sphere, or less than a hemisphere. The head is fashioned from pressed sheet metal that is a good conductor of electricity, and on its exterior, convex face, the head is provided with a multiplicity of electrodes 2 that are fashioned by striking up or stamping the eleci trodes in the form of lugs or spurs from the metal of the head. These electrodes, which are interspersed equidistantly one from another over the area of the outer face of the head, are disposed like wedges, or triangles, with their apices all pointing downwardly in order that the rays or waves emanating from the electrodes may flow as indicated by the dotted lines in Figure 1, to the subject or patient being treated.

The hollow head is closed by the use of a cap plate 3 preferably of insulating material, flat, and circular in shape, with an open center, and the metallic head is fashioned with an annular flange 4 that is secured on the periphery of the plate 3 by screws 5.

The conductor wire 6 electric current is loosely attached to the plate by means of a sleeve 7 through which the conductor or wire passes, and the sleeve has an eye or loop 8 that engages with the screw eye 9 secured in the plate 3 to anchor the attachment.

The conductor passes through a hole in the cap plate, and is electrically connected with the hollow head by a suitable terminal 10, within the head as indicated in Figure 2. The current from the conductor is thus supplied to the head as a whole, and the waves or rays emanate from the exterior of the head through the points of the electrodes 2. I

The metal head is provided with a central, inner band or annular flange 1a that surrounds the gage-post or supporting bar 11, and this gage post, with its rounded supporting end 12 is fashioned of insulating material, as glass, hard rubber, or other suitable material that may be brought in contact with the subject or patient being treated. The gage-post is used as a support for the applicator head, and the latter is adjustable therein toward or from the lower rounded end 12 of the post.

At its upper end the post is fashioned with a pair of perforated ears 13, and by means of a suitable pivot 14, the handle bar 15 is connected with the post in order that the instrument may be manually manipulated during the course of treatments.

The post passes through the annular, inner flange 1a of the head and also through a central hole in the cap plate 3, and by means of a clamp sleeve 16 surrounding the post and situated in the hole of the cap the electrode-head is secured in adjusted position on the post. The upper end of the sleeve is split and exteriorly threaded as at 1'7, and the lower end of the sleeve is externally threaded as at 18, the split, resilient portion of the sleeve being located above the plate and the from a suitable source of 7 externally threaded lower end of the sleeve being located below the plate, or within the hollow head.

Within the head a supporting nut 19 is threaded on the end 18 of the sleeve, and exterior of the head a clamp nut having a tapering interior bore and indicated as 20, is threaded on the resilient split sleeve.

Thus, with the clamp nut 20 loosened, the head, guided by its inner annular flange, and the plate guided by the sleeve, may be bodily adjusted by sliding on the post, and when the desired position of the head is attained, by turning the nut 20 the head may be clamped in position for use on the gage post.

In use, the rounded end 12 of the post is rested upon the subject or patient to be treated while the applicator is manipulated and retained by the hand that grasps the pivoted handle bar 15, and

one skilled in the art may with facility utilize the applicator for performing its various functions with eificienoy, accuracy and reliability.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:--

The combination in a therapeutic applicator for discharging high frequency electric currents, of an electrode-head of sheet metal, spurs struck up from the sheet metal and forming exterior electrodes, an insulated guide plate for the electrode-head and a guide flange on the electrode-head for co-action with the post, means for securing the electrode-head in adjusted position on the post, and electrical, connections to the electrode-head.
